Magnetoelastic anisotropy of amorphous microwires

Journal of Magnetism and Magnetic Materials, 2003
Anisotropy constants of amorphous microwires with positive, negative, and nearly zero magnetostriction, are calculated as function of wire dimensions starting from the distribution of internal stresses induced during preparation. Some basic aspects of their magnetic behavior are subsequently discussed, in correlation with earlier experimental results.

Dynamic hysteresis in magnetostrictive amorphous microwires

IEEE Transactions on Magnetics, 2002
Summary form only given. Amorphous magnetostrictive wires exhibit very rapid bistable magnetisation reversal (large Barkhausen jump). This property makes them unique for applications in security sensors and pulse generators. As operational frequencies become progressively higher, there is an interest in studying the magnetisation reversal in bistable ...

Structure and properties of an amorphous microwire

Metal Science and Heat Treatment, 1992
,Problems of the production, investigation, and use of a microwire with an amorphous vein structure are discussed. It is determined that the magnetic properties of microwires depend heavily on the domain structure. It is established that a domain-free structure, which is characterized by a high coercive force, is also possible in a microwire.

Explosive transition in amorphous microwire

Technical Physics, 2017
An amorphous microwire in a glass shell offers a quick thermal response and can be rapidly heated to the crystallization point. When heated by a current pulse with a small amplitude and duration, the wire passes from the amorphous to microcrystalline state.

Amorphous microwires in microwave fields

Fourth International Kharkov Symposium 'Physics and Engineering of Millimeter and Sub-Millimeter Waves'. Symposium Proceedings (Cat. No.01EX429), 2002
The results of ferromagnetic resonance measurements for microwires in the 75 GHz and 10 GHz frequency bands over a wide temperature range (300 K-0.5 K) are presented. Discussion and analysis of the magnetospectroscopy results are given in the paper. The possible reasons for the magnetoimpedance jump revealed in the vicinity of the low-field area are ...

Dipolar Interaction Between Amorphous Microwires

IEEE Transactions on Magnetics, 2008
We present a model for the description of the magnetostatic interaction between two glass-coated amorphous microwires with positive magnetostriction. We report the results of dipolar field calculations based on this model as well as results of measurements on microwires with their ends separated.

Metamaterials from Amorphous Ferromagnetic Microwires: Interaction between Microwires

Solid State Phenomena, 2009
For inhomogeneous mediums the оptical Magnus effect has been derived. The metamaterials fabricated from amorphous ferromagnet Co-Fe-Cr-B-Si microwires are shown to exhibit a negative refractive index for electromagnetic waves over wide scale of GHz frequencies.

Surface Crystallization and Magnetization-Reversal Processes in Amorphous Microwires

Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques, 2023
The bulk-inhomogeneous crystallization of amorphous microwires of composition Fe73.8Cu1Nb3.1B9.1Si13 has been studied. An assumption was put forward about the influence of the non-uniform distribution of tensile and compressive stresses in the bulk of microwires on their crystallization.
